NutraBio L-Citrulline is a single-ingredient amino acid supplement, offering 100% label transparency. Each serving provides 2 grams of L-Citrulline. Based on current research, this dosage is considered underdosed for many common applications of L-Citrulline, such as supporting exercise performance or nitric oxide production, which often require higher amounts. The product received an N+ Score of 29, earning an 'F' grade, reflecting its poor ingredient adequacy despite its simplicity. While it offers pure L-Citrulline, consumers seeking clinically effective dosages may need to adjust their serving size. This product is best suited for individuals who prefer a standalone L-Citrulline supplement and are willing to dose accordingly.
